Programming OSD with FTDI converter

[StarLog]

So i connected the cables between the two, when i run the OSD update tool, it says cannot contact bootloader.

Any suggestions.

check if you have the FTDI converters usb driver.

OK, found the drivers, and now it says waiting for MAVlink heartbeat.

Where does that come from.?

 

[DroneTalks]

ok so you installed the drivers, does that message appear when you try to use the FTDI converter?

I believe I know what the issues are.

I only have 3 wires coming from the APM to the OSD.

Will check what is missing tonight, then give it another go.

I am so down and out. When the OSD is plugged into the FTDI converter, the video passes thru to my Fat Shark, and I see the message, waiting on the heartbeat.

When I then plug in the cable of +5vdc, ground and RX. there is no video out.

Guess I need to take a break.

Looked somemore, believe that 5vdc is not being supplied from the cable to the telemetry port.

If I stimulate with external 5vdc, it works.
